I'm trying to get started with the gsl-ruby library - thought I'd start
with calculating mean of an array. I'm following the example on
http://rb-gsl.rubyforge.org/stats.html. But I run into this:
require("gsl")
=> true
irb(main):002:0> v = Vector[1..7]
NameError: uninitialized constant Vector from (irb):2
Isn't Vector in the core?... so I did this
irb(main):003:0> require 'matrix'
=> true
irb(main):004:0> v = Vector[1..7]
=> Vector[1..7]
irb(main):005:0> v.mean
NoMethodError: undefined method `mean' for Vector[1..7]:Vector
from (irb):5
It appears my GSL is not installed or something....? I would really
appreciate some guidance. Thank you.
I have installed libgsl-ruby1.8, libgsl0ldbl, libgsl-ruby, and gsl-bin
